Webb29 okt. 2024 · Viscosity modifiers help reduce the rate of viscosity change when temperatures rise or fall. This helps the lubricant provide better performance over a broader temperature range. Polymers and copolymers of olefins tend to expand as the temperature rises, counteracting the oil’s tendency to thin. WebbIngestion of hydrocarbons, such as petroleum distillates (eg, gasoline, kerosene, mineral oil, lamp oil, paint thinners), results in minimal systemic effects but can cause severe aspiration pneumonitis . Toxic potential mainly depends on viscosity, measured in Saybolt seconds universal (SSU).

WebbProperties of the main fractions of crude oil. Viscosity: This refers to the ease of flow of a liquid.High viscosity liquids are thick and flow less easily. If the number of carbon atoms increases, the attraction between the hydrocarbon molecules also increases which results in the liquid becoming more viscous with the increasing length of the hydrocarbon chain.

WebbFractional distillation is the process by which oil refineries separate crude oil into different, more useful hydrocarbon products based on their relative molecular weights in a distillation tower. This is the first step in the processing of crude oil, and it is considered to be the main separation process as it performs the initial rough separation of the different fuels. Webb1 jan. 1996 · In general, the viscosity of a hydrocarbon decreases monotonically as the temperature increases, and the logarithm of viscosity decreases almost linearly with increasing temperature. At temperatures near and above the normal boiling point this linearity disappears for most liquids.
